Getting old am I, few minutes of "where the heck did I see that" coupled with the "when you going to learn to write down sources"
Reply #66 in this thread. The photo shots, instructions, change fluid when it turns dark. Now I'm really gonna step on my own tongue but we are cutting metal, generates heat, creates oxides, we don't see em but they be there. Tumblers by the nature of the process remove these oxides which turn the solution dark.
So the thought is, just to watch the fluid and rinse media, change fluid as necessary to keep it clean. As the dirt is removed from the parts and left in solution it'll just be transferred back onto the piece. So the drop of dawn dishsoap applied that has been mentioned must be to encapsulate the crud, reducing its transfer back. Still have to change fluids tho.
Also came across the table again indicates a 5-1 media - part ratio mix for minimal part to part contact. The more delicate the part the greater the ratio.
Patience, to which I personally have none, but I can wait. Coffee and donuts are well suited for those "Wait" times.
Back to beating them pieces to a shine

Edit photo 2 pieces. One on left from tumbler with dry BB's over night. Purpose was just to debur the edges which it did. Can tell no tool marks removed. Wanted to see just how well the BB process performed under a harsh case. Did fine.
Piece on right is from a dry walnut 2 day tumbler session. Its getting a shine but is obvious that the middle stage is missing. The media with compound to remove the finer tool marks. As this piece has multiple curved surfaces thinking the walnut shells with impregnated grit is in order.
Going for a three stage process then, I'll be back
